So, my Brother-in-law and I are planning on getting 20 Acres, and our main focus will be a shipping container home for me. It will be 6 53x8 containers, stacked 2 high, and 3 across. My biggest issue at this point will be installing doors on all three bottom containers, and reversing the outside doors on the top so it can be opened from the inside. As well as figuring out how to seal the containers from the weather. Our plan is to use roofing tar and heavy duty plastic tarps. We will be using a Plasma cutter to remove the walls and Oxy-Acetalene torches to create walls for bathroom etc. Has anyone created a mutliple container house that knows how to fix these issues? Figured the roofing tar will be sufficient, but still not sure how to invert the doors.
